    I get random -but consistent - CryptographicException: Bad Data exceptions
    when using TripleDES encryption.

    For instance, when looping over i = 0 - 100, I always get errors when
    tryping to decrypt the numbers 60 and 96.
    for( int i = 0; i < 100; i++ ){

    try

    {

    string t = StringUtility.EncryptString( i.ToString() );

    Response.Write( t + " : " );

    Response.Write( StringUtility.DecryptString( t ) + "<br>" );

    }

    catch( Exception )

    {

    Response.Write( i + " bad data.<br>" );

    }

    }
